Minimally Invasive-Off-Pump Heart Surgery
The majority of Coronary Artery Bypass Graft (CABG) procedures are done with the circulatory support of cardiopulmonary bypass (on- pump), but this has been documented as having associated risks such as myocardial ischemia, neurological deficits, stroke, bleeding disorders, renal failure, and pulmonary complications. Off pump CABG (OPCAB), or coronary bypass without cardiopulmonary support, has been developed as a surgical technique to reduce the incidence of risks associated with on-pump CABG and potentially improve clinical outcomes. Minimally invasive off pump coronary artery bypass (MIS-OPCAB) techniques have also been developed to allow surgical access without a full sternotomy which can shorten length of stay in both the post- surgical intensive care unit and the overall time in the hospital. This document provides an overview of these products used in these procedures and current evidence regarding their use.
